Definitions

  • the present invention relates to apparatus and methods for controlling the configuration of a printer and, in particular embodiments, for allowing a user to select a printer default configuration from a plurality of preset default configurations to control a printer connected in a multiple work station network.
  • a default configuration In a typical computer printer, it is necessary to establish a default configuration.
  • the printer has a default configuration set by the user or preset by the manufacturer.
  • Default configurations comprise sets of instructions for controlling certain parameters of the printing operations performed by the printer, including, but not limited to, fonts, paper sizes, page description languages, finishing options and stackers. Data or instructions for setting the default configuration are typically stored in a memory circuit within the printer.
  • a typical network system e.g., wherein one or more printers are connected, through a network communications link, to a plurality of individual work stations (e.g., personal computer terminals), each printer will have a preset default configuration, as discussed above. Each work station accessing a printer must operate with the default configuration set for that printer.
  • each printer may have a default configuration different from the default configuration set for the other printers in the network. Any one printer may be selectively accessed by a work station user by selecting that printer's network port. In this regard, by connecting a plurality of printers in the network through a corresponding plurality of network ports, a work station user may select the printer (and, thus, the default configuration set for that printer) to accommodate that user's printing needs.
  • the cost of including multiple printers in a network can be relatively high, especially where a large number of printers (and default configurations) are required.
  • the physical capabilities of the work stations or the network communications link may limit the number of printer network ports (and, thus, the number of printers having different default configurations) operable in the network.
  • a device typically has a unique communications protocol address for each protocol compatible therewith.
  • the print server responds to multiple protocol addresses. Each address to which the print server responds is uniquely associated with a default configuration.
  • a printer is selectively controlled to operate as any one of a plurality of "Virtual Printers.”
  • “Virtual Printer” has a default configuration which differs from the default configuration of the other "Virtual Printers.”
  • a single printer connected in a network through a single printer network interface can be operated in accordance with any one of the plural default configurations.
  • a work station user selects a desired printer default configuration by selecting a unique communications protocol address associated with that default configuration. By directing the print data to the selected communications protocol address, the printer automatically assumes the default configuration associated with that address.
  • Default configuration setting circuitry provided, e.g., in a circuit card installed in the printer, is programmed to respond to the communications protocol address and, via a look-up table, provide instructions for implementing the default configuration associated with the address. The printer is then configured in accordance with the selected default configuration. If the same work station user or another work station user desires a different printer default configuration, the new"d fault configuration is selected by that user and print data sent from that work station is directed to the communications protocol address associated with the new default configuration.
  • the default configuration setting circuitry provides instructions for implementing the default configuration associated with the communications protocol address in the manner discussed above, such that the printer is then configured in accordance with the new default configuration.
  • print data for a plurality of printer default configurations can be sent through a single printer network interface to a single printer.
  • the printer can be configured in accordance with any one of the plural default configurations, thus obviating the need to connect a plurality of printers (each having a different default configuration) through a plurality of printer ports in the network.
  • considerable cost in providing a separate printer for each default configuration can be avoided.
  • the number of printer ports needed in the network may be reduced.
  • FIGURE 1 is a block diagram of a computer network employing an embodiment of the present invention.
  • FIGURE 2 is a block diagram representing the computer network of Figure 1, as perceived by a work station user.
  • FIGURE 3 is a block diagram representing a look-up table of a printer default configuration control circuit indexed by the communications protocol address in accordance with an embodiment of the present invention.
  • FIGURE 4 is a block diagram of the network shown in Figure 1, with a further representation of internal architecture of the printer shown in Figure 1.
  • a printer is selectively controlled to operate as any one of a plurality of "Virtual Printers.”
  • Each Virtual Printer has a default configuration which differs from the default configuration of the other Virtual Printers.
  • a single printer connected in a network through a single printer network interface can be operated in accordance with any one of the plural default configurations.
  • Figure 1 is a block diagram of a computer network 10 in which a number of individual work stations are connected, through a network communications link, to a printer station.

  • the printer 16, with the control circuit 22, has multiple default configurations, each designated as a "Virtual Printer". Circuit 22 could be implemented in hardware and/or software. Each Virtual Printer is associated with a unique communications protocol address. When accessing the printer, the user of the accessing work station, e.g., work station 12, directs the print job to the communications protocol address of the Virtual Printer with the default configuration desired by the user.
  • the circuit 22 upon receiving the print job from work station 12, the circuit 22 recognizes the communications protocol address as being associated with one of the Virtual Printers. The circuit 22 then provides the printer 16 with printer default configuration instructions for the Virtual Printer associated with the communications protocol address. In response to the instructions from circuit 22, the printer 16 is automatically set to the default configuration specified for the Virtual Printer associated with the communications protocol address selected at the work station 12, without manual action on the operator control panel of the printer. With the printer 16 set in accordance with the selected default configuration, the print job from the work station 12 is processed by the printer.
  • the circuit 22 includes an address processing circuit and a look-up table and associated memory for storing a plurality of default configuration instruction sets with a corresponding plurality of communications protocol addresses.
  • the circuit 22 receives a print data signal from the work station 12 directed to the selected communications protocol address.
  • the circuit 22 processes the communications protocol address and provides the default configuration instruction set corresponding to the communications protocol address in the look-up table, for setting the printer 16 with a particular default configuration (or Virtual Printer) .
  • the work station user can set the physical printer 16 to any one of the plurality of default configurations (Virtual Printers) by selecting the associated communications protocol address and sending the print job signals to that address.

Abstract

Un utilisateur d'un poste de travail (12, 14) sélectionne une configuration implicite désirée d'une imprimante (16). Cela fait, une adresse exclusivement associée à la configuration implicite sélectionnée est annexée aux données d'impression envoyées du poste de travail (12, 14) à l'imprimante (16). Un circuit de réglage (22) de la configuration implicite, ménagé, par ex., dans une carte de circuit placée dans l'imprimante (16), réceptionne l'adresse et, par l'intermédiaire d'une table à consulter, donne des instructions pour mettre en place la configuration implicite associée à l'adresse. L'imprimante (16) est ensuite configurée selon la configuration implicite sélectionnée.
